Roman furniture was made of stone, wood and bronze. The dining couches, which replaced chairs, were richly decorated. Chairs followed earlier Greek forms. Tapestery and Rugs came to Rome from Egypt. Fabrics were first imported from Asia Minor. Roman walls were hung with tapestry and pillars decorated with textiles. Silk was imported from China. Later the silk worms were stolen from China and the industry was established in Europe. The Romans were highly skilled glass workers. Glass was made for both utilitarian and decorative purposes. Bronze used in houseware items was vast. Small pieces of furniture, like stools, were made wholly of bronze. Lighting fixtures played a large part in the decoration of the interior. Enormous quantities of silver pieces went into the making of platters and similar pieces of holloware. Statuary in bronze decorated the more important interiors. Themes of decorating were many and most came from Greek sources. The jagged Ascanthus leaf is by far the most common. The lion was very popular especially the mask and the paws. The head of the ram, a sacrificial animal, commonly ornamented altars and candelabras. The eagle, representing Jupiter, was the symbolic standard of the roman legion. Roman grotesques, fantastic figures of humans and animals were a discovery of the Golden House of Emperor Neru. They were found below ground in a grotto. The evidence is overwhelming that affluent Romans lived a lavish lifestyle. Interiors reflected their taste for luxury and sumpuous pleasures.
